FEED-GAGE.

Specification of Letters Patent.

Patented Jan. 2, 1906.

Application filed May 25, 1905. Serial No. 262,286.

To all whom it may concern:

Be it known that I, LA ROY E. TAIT, a citizen of the United States,residing at Redcloud, in the county of Webster and State of Nebraska,have invented a new and useful Feed-Gage; and I do hereby declare thefol lowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The invention relates to feed gages for platen printing-presses, and hasfor its object to provide an exceedingly simple, inexpensive, anddurable device of this. character provided with means for doing positiveand accurate register work which is so essential in color-work. [t Afurther object of the invention is to provide a simple and efficientclamp whereby the feed-gage may be readily clamped to the tympan-sheetwithout injuring said sheet, said clamp being adapted to clamp orrelease in a most simple yet effective manner.

With these and other objects in view my invention consists in the novelconstruction I and arrangement of parts hereinafter described and shown,and particularly pointed out in the appended claims.

In the drawings forming part of this specification, and in which likenumerals of reference designate corresponding parts, Figure 1 is a planview of afeed-gage constructed in accordance with my invention and shownap plied. Fig. 2 is a perspective view of the device. Fig. 3 is a sideelevation. Fig. 4 is a view of an ordinary feed gage having my clampingdevice applied thereto. Fig. 5 is a perspective view of my clamp. Fig. 6is a detail perspective view of the upper member 4. Fig. 7 is alongitudinal-sectional view of the feed-gage.

Referring to the drawings, 1 designates the platen of a printing-press,and 2 the tympansheet to which my device is designed to be at tached,and 3 the sheet of paper which is fed to the printing-press.

The gage is constructed of sheet-copper or other suitable metal. Thegag'e is composed of sheet metal having upper and lower members 4 and 5.Lugs 6 and 7 are formed out of the upper member 4, as shown in Figs. 1

lever is engaged by an inclined portion 11 of the member 4, whereby saidlever is held in engagement with said spring. A lug 12 is also formedintegral with the member 4, against which the sheets of paper are fed inprinting. In practice the lever 9 is engaged by the gripper-bar, whichpresses it down, whereby the lower part of said lever is adapted toshove the sheet of paper out to the register-line, whereby accurate workis accomplished.

My feed-gage is adapted to be secured to the tympan-sheet by means of aclamp consisting of upper and lower members 12 and '13 and is providedwith a shank 14 and is secured to the feed-gage by means of a rivet 15,which pierces the upper and lower members of the fcedgage and the lowermember of the clamp and which holds them securely together. The clamp isprovided with an upward projection 16, by which it is swung into and outof engagement with the feed-gage, as desired.

The feed gage is secured to the tympansheet by means of the clamp asfollows: A slit 17 is cut into said tympan-sheet, and said tympan-sheetis engaged by the upper and lower members of the feed-gage, and the saidmembers are engaged in like manner by the clamp, whereby the device isfirmly secured to the tympan-sheet.

What I claim is '1. A feed-gage consisting of upper and lower members, alever mounted in a pair of upturned projections formed integral withsaid upper member, substantially as shown, a spring mounted on the rearportion of said upper member and engaging said lever, a lug also formedintegral with said upper member and adapted to limit the action of saidspringpressure, said lever being adapted to engage the gripper-bar of aprinting-press, substantially as and for the purpose described.

2. A feed-gage having upper and lower members, said members beingadapted to receive a tympan-sheet between them, a sheetmetal clamp bentupon itself, having upper brought into and out of engagement with theand lower members and adapted to receive feed-gage, substantially asdescribed. 10 said first-named members between them, sub- In testimonywhereof I have hereto aflixed stantially as described. my signature inthe presence of two witnesses.
